as quite a number of questions show up when you search for mips - 41 currently, although I think some might not fit under the spirit of such a tag

there is a tag for [x86], which has 47 questions tagged currently

if I click on 'Improve Tag Wiki' for an existing tag I get:

You do not yet have tag wiki edit privileges. Your edit will be placed in a queue until it is peer reviewed., which is expected, but if I enter a non-existent tag from the TAGS page there is no button or prompt to add a new tag.

I just attempted to add on a single question as an edit, so perhaps it needs to be peer reviewed first.

I guess my question is, how can I propose the description / edit for the tag wiki for a new tag if I can't see it yet because it is waiting for peer review?
